Question about 2007 Infiniti G35 Sedan Sport Sedan

1 Answer

I have the same problem, 2003 G35.

Seems to be heat related. All is normal, whether the air cond. is on or off, until the car has been running for awhile. Then the console shuts down while the air cond. goes to high, in the recirculating mode. If it's very hot outside, then this will happen upon starting the car.

Although the console goes off, I can still operate the radio from the steering wheel controls.

I have checked fuses, which seem to be ok.

That looks you getting problem with the Alternator
Maybe the Alternator is weak
May sure the battery has required voltage,been off at all
Then start the vehicles, if voltage go up, means of battery level.
If voltage not go up.May sure battery is in good condition.

SOURCE: 2003 Infiniti G35. Radio turns off, air conditioner full blast.

Hello, The problem with the A/C controls and center console functions lies in the power circuit of the stereo unit. The solution for this is to replace the head unit via the dealership (very expensive) OR rebuild/repair your original unit. Unfortunately this is not a fix you can do at home - it does require electronic bench work.

Please feel free to contact me for more information. Our company does offer this repair service nationwide. I'm sure we can save you both time and money.

Kind regards,
Robert Cruz

SOURCE: I have a car 2003

Both heat and air conditioning system turns on and you cannot control climate control or the radio.But you can operate it by push buttons on steering wheels.------------ There are many other users too,facing this problem.there was a service bulletin by the Infiniti car service centers.Its a recall for this car. INTRODUCTION On some model year 2003 G35 Sedans manufactured through August 21, 2002, the audio and temperature controls may not operate as expected. When using the audio equipment or the temperature controls, the unit may become inoperative. In some cases, this can be corrected by turning the ignition switch off and back on again. In other cases, the unit remains inoperative and requires service by an Infiniti technician. To prevent this condition, Infiniti has initiated a Voluntary Service Campaign to replace the audio finisher circuit board on these vehicles. Use Infiniti Net to confirm if a specific vehicle is affected by this service campaign (P3104). IDENTIFICATION NUMBER Nissan has assigned identification number P3104 to this campaign. This number must appear on all communications and documentation of any nature dealing with this campaign. NUMBER OF VEHICLES POTENTIALLY AFFECTED The number of vehicles potentially affected is approximately 23,600.2/16 DEALER RESPONSIBILITY It is the Infiniti dealer's responsibility to check Infiniti Net for the campaign status on each vehicle falling within the range of this Voluntary Service Campaign (P3104) that enters the service department. This includes vehicles purchased from private parties or presented by transient (tourist) owners and vehicles in an Infiniti dealer's inventory. NOTE: The vehicle may also be affected by the 2003 G35 Sedan Headlamp Adjuster Voluntary Safety Recall Campaign (R2022). ----------------- For further help,click on this link directly:--- ----------------- The dealer will repair it for free. as per infiniti service bulletin. This will help.Thanks.Helpmech.

On my 2009 1500 silverado, the driver side air cond blows HOT air as if the heat is on, but if you cycle the driver side temp control up then back down several times or turn the truck off like short trips...

There is a damper that controls whether heat or cooling or somewhere between that is controlled by the temperature controls. A separate system is controlling the passenger side and the driver side heating and cooling. I hope this is still under warrantee. If not it might be a big job to diagnose whether the problem is in the heat and cool controller, the wiring or the damper device. I hope this helps.
